QUILTING-MACHINE.

SPECIFICATION forming part of Letters Patent No, 289,884, dated December 11,1853.

A pplication filed September I, 1853. (No model.)

To aZZ tail/0722, may concern:

Be it known that I. ADAM BRENZINGER, of the city, county, and State of New York, have invented certain new and useful Improvements in Quiltingdllachines, of which the following is a specification.

This invention has. reference to certain improvements in quilting-machines,whereby not only diagonally-intersecting lines of stitches, which form the so-called diamonds, but also a number of different ornamental patternsnnay be produced by the same mechanism.

The invention consists, essentially, of avertically reciprocating needle bar having a series of needles arranged in three rows, the intermediate row having twice as many needles as the first and third rows, with mechanism by which the fabric is fed forward and simultaneously in lateral direction.

The invention consists, secondly, of the construction of the needle-bar in which three rows of needles are arranged, of which the intermediate row has twice as many needles as the first and third rows, which are located diagonally in line with and equidistantly from needles being supported by two parallel needlebars, the front bar of which is provided with slots to regulate the set-screws of the intermediate row of needles.

In the accompanying drawings, Figure 1 representsa front elevation of my improved quiltingmachine. Fig. 2 is a plan of the same. Fig. 3 is a diagram showing the relative arrangement of the needles on the needle-bar. Fig. 4 is an end elevation of the quilting-machine. Figs. 5 and 6 are respectively a detail plan and a side view of the needle-bar, the

latter figure having a part broken away. Figs. 7, 8, and 9 are diagrams showing different patterns that can be stitched on my improved quilting-machine.

The essential feature of my invention consists of the construction of the needle-bar, which I have shown in connection with a quilting-machine constructed on the type shown in the patent granted to August Beck, No. 279,632, dated June 19, 1883'. In this machine a series of organized sewing mechanisms are arranged on a carriage,B, moving on anti-fricmechanism, which is fully described in the patent referred to.

. The fabric is fed in the usual manner over the cloth-table by intermitt-ently-actuated feed rollers D D. The needle-bar O is vertically reciprocated by suitable mechanism, and provided with a series of needles, which are arranged in three distinct rows, one behind the other. The middle row contains twice as many needles as either the first or third row, which needles are diagonally in line with those of the outer rows and equidistantly from the same.

For supportingthe needles in the order described, the needle-bar is made of two parallel bars, (I d, of which the rear bar is made thicker than the front bar, both being pro vided with grooves e for the shanks of the needles, and with set-screws ff, by which the needles are retainedin the grooves e e of said bars, as shown in Figs. 5 and 6. The rear bar, [1, serves to support the needles of the second and third rows, while the front bar supports only the needles of the first-row.

The front bar, (1, is provided with inclined slots d so that the set-screws of the needles of the second row can be easily adjusted from the front of the needlabar. The shuttles and shuttle-races are arranged below the clothtable, and are made to correspond to the positions of the needles. They are not shown in the drawings, as they are made in the usual manner and require no special description.

When the fabric to be quilted is fed forward by the feed-rollers D and the carriage B, that supports the organized sewing mechanisms,

moved simultaneously in a lateral direction, diagonal lines of stitches are formed on the material to be quilted. By the lateral motion of the carriage in opposite directions, the direction of the diagonal lines of stitches is reversed, whereby'each needle produces a zigzag line of stitches which meets the zigzag lines of stitches of the adjoining needles at the angles of said lines, so as to impart thereby to the fabthe needles of the first and third rows, devices ric the character of intercrossing diagonal I lines of stitches that form regular diamonds, as shown in Fig. 7.

If a suitable pattern-cam is employed, by which the lateral motion of the fabric is interrupted at certain intervals, a number of different designs, such as are shown in Figs. 8 and 9, can be produced, by which variegated effects may be imparted to the quilted fabrics. Quilted linings of different designs can thereby be produced in a quick, economical, and effective manner by the conjoint action of mechanisms for moving the fabric and the action of the needle-bar having three independent rows of needles.

I am aware that aquilting-machine having a needle-bar with two rows of needles, of which the second is behind the first row and alternating therewith, is well known,and I do not claim the same.

Having thus described my invention,I claim as new and desire to secure by Letters Patent 1. In a quilting-machine,the combination of a Vertically-reciprocating needle-bar having a series of needles arranged in three rows, one behind the other, the intermediate row having twice as many needles as the first or third row, theneedles of said intermediate row being set in the diagonal line with and equidistant from for feeding the fabric forward beneath the needles, and mechanism whereby laterally-reciprocating motion is imparted to the entire sewing mechanisms, substantially as set forth.

2. In a quilting-machine, a needle-bar constructed withthree rows of needles, one behind the other, the intermediate row having twice as many needles as the first or third row, which needles are located in the diagonal line with and equidistant from the needles of the first and third rows,substantially as specified, in combination with means for operating the needle-bar.

3. In a quilting-machine, the combination of a bar adapted to receive a set of needles, means for clamping said needles thereto, a supplemental bar adapted to receive two sets of needles, and set-screws for clamping the same to either side of said supplemental bar, the h first bar being provided with slots, whereby access may be had to the set-screws between the bars for adjusting the same, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

ADAM, BRENZINGER.
